How to use CSV Multivalue Exploder

Turn one declared list column into a normalized record set. Choose a literal separator or a JSON string-array grammar and explicitly decide how empty lists participate.

  1. Enter input, list column, literal separator.
  2. Choose the settings for csv multivalue exploder, then run the tool.
  3. Review the result and any limitations before copying or downloading it.

Good to know

  • Up to100,000 input characters,5000 records and100 columns per table. Downloads quote cells, protect formula-like values and disambiguate colliding exported headers.
  • One selected column, at most 1000 members per cell and5000 output records. Literal members retain whitespace; no Cartesian products or inferred separators.
  • Processing is local. Output is limited to 1,000,000 text characters unless a stricter file limit is stated.

Common questions

Can a separator inside a list item be escaped?

Literal mode has no escape grammar. Use a JSON string array when items contain the chosen separator.

Is this input sent to a server?

No. The application processes this input inside your browser tab and does not save it to persistent storage.
